Answer:
y= 2x+1
Step-by-step explanation:
Line parallel to y = 2x + 4
And that goes through the point (2,5)
-----------
Parallel lines have equal slope, so it will be in the form of y= 2x+b
Let's find the value of y-intercept (b) by using the given point:
So the line is: y= 2x+1
Meaning there's only 1 real root, complete the square and you get the answer.
We're going to use this formula, so if x² = 4x² then x = 2x
and if y² = 1 then y = 1
Straight to formula
Because (2x+1)² is basically (2x+1)(2x+1), we get the same value of x.
So the answer is x = -1/2
(When D>0, there are 2 real roots.)
(When D=0, there are only 1 real root.)
(When D<0, there are no real roots, but 2 complex roots.)
1/2b*h = (b*h)/2
That’s how you calculate the area of a triangle
Let the number be x.
(2/3)x = 3 1/2 + (3/8)x
(2/3)x - (3/8)x = 3 1/2
(8*2 - 3*3)/(8*3) x = 7/2
(16 - 9)/24 x = 7/2
(7/24)x = 7/2
7x/24 = 7/2 Divide both sides by 7
x/24 = 1/2
x = 24*1/2
x = 12
The number is 12.
